Q. Define: rms value of AC.
RMS value of a.c.
The rms value of alternating current is described as that value of the steady current which when passed through a resistor for a given time will generate the same amount of heat as generated by an alternating current when passed through the same resistor for the same time.

show that in a glass prism that the refractive index n = sin1/2(A+Dmin)/sin1/2A where a = refracting angle. hence if the angle of incidence i on oan air boundary is 60degrees. calc
Why does the charge on the outer surface of a parallel plate capacitor doesn't change when it is connected by a battery. only inner surface charge gets affected. Why??
Volume resistance: The resistance provided to the current which flows through the material is called volume resistance. For a cube of unit dimensions this is called volume resisti
MOVEMENT OF CHARGE: Although electric current is referred to as the flow of electrons through a conductor, it should be noted that more exactly, any movement of electric charge
